` ready connection of thearticleto a piece of furniture. n The casterf comprises other points of novelty andadvantagewhichwlth the foregoing will be set forthindetail in lthe following description, wherein lwill disclose' quite `fully that 1 forni of embodiment of the inventionwhich have selected` `for illustration in `the ,drawings accom panying and forming part of the present speciiication-` This showing is intended to enable those versed inI the art to practice the invention. Obviously 1 do not limitinyself thereto; 1 may deviate therefrom in various respects within"`the scope ofthefiiivention defined by the claims following said description.

Referring to said drawings:

Figure 1 4aver-tical sectional view of a caster and associatedparts involving the invention, showing the same in correlation with an article of furniture but partially illustrated, the dotted lines representing a way of dismounting the caster.

Fig. 2 is a practically similar view at virtually right angles but only the upper' part v of the caster showing a Fig. 3 is a horizontal section on the line 3&3 of Fig. 1, looking in the direction of the arrows. e

Like characters bracket as 2, and while this bracket Iandcertain of the other parts in fact may be of any suitable material, pressed rnetal is desirable,

` although malleable iron is another metal thatcan be used. This bracket 2 includes mating arms as 3 perforated to receive the shaft Ll.l Said shaft extends `through the wheel 5 for example virtually in the way shown in` my prior Letters Patent No. 832,794 of October 9, 1906, to which reference may be had. The body of the bracket-2 externally thereof has the race 6 to receive the refer to like parts `throughout the several views. The caster includes in its `structure a financera.,,1;`

l baue v er which eine :maybe any desirable number;` l, `The upper` `portion `of `said bracket is furnished `with an inwardly extending flat flange,theinner"edge of which presents a circular` opening 9 to receive a pivot or stud "as 10,"although"`thelpivot `or stud it might be `observed at this point, does not extend directly through said circular opening 9. The pivot orjstud jlO will be described more in detail* hereinafter. Surlnounting the body Iof *the* bracket isl acupi-shaped head 11, the `:inner rounded `marginal a `surface of which presents race"eomplemental" tothe race 6 for receiving the" `balls 7,* thus maintaining fthe' balls in `position. *Thefcup-shaped head a "11 hasin theupper "side thereof the practicallycircularfopening 12,` the wall of `which `has a' downturned flange 13, the lower end of which is outturned `as at 14, the `downturned flange extending through the `opening 9 to `which 1 h alve" already referred, and the flange "14 overlying the inwardly flanged portion `15of "the body of the bracket 2. Y

Thepivot or stud 101` to `which 1 have already referred, extends comparatively `freely through "the openingtfll?, *l its lower l reduced end is provided with a circumferential groove 16 into which the inner rounded portion of the pendent flange 13 fits. The pivot or stud 10 extends above the cupshaped head 11 and terminates at its upper end in a circular flange 17, constituting a e convenient head.

Surmounting the head 11 is a cup-like part 18,` the bottom 19 of which is as shown ofconcavdconvex form in `cross section, the convex face being up yet slightly below the This part 18 is attached to the article of whatever character it may be with which it is desired to associate the caster. Such an, article is shown at 20, and it will be assumed to be a leg of a piece of furniture. rllhe part 19 has its marginal flange fitted centrally to the under surface of the leg 20, and when this is done several screws as 21 can be passed through perforations in the `portion `19 and into the leg 2O.` The concavo convex portion 19 as shown has a radial slot 22 preferably but not essentially of key-hole form with the large part out and `with the narrow portion in position to re- `ceive the pivot or stud 10. The portion 19 it might be observed at this time possesses a certain amount of `resiliency which is of advantage 1n maintaining the parte 1n as edge of themarginal flange of said part 18.

sembled relation and against accidental separation, or a suitable spring `fortl1is purpose may be placedat.orsunderfthe'lower Harige of stud 1 It will be supposed that the cup-shaped part 18 is connected to a furniture leg asV p 20andthlatthe ebracket2-and parts carried thereby including the pivot -or .stud ,10 are disconnected from said part 18 as illustrated .practicallyffor-exampledn Eig. 1.
